- how often does fresh water clam reproduce-Freshwater mussels have an unusual and complex mode of reproduction, which includes a brief, obligatory stage as a parasite on a fish. … While attempting to eat the lure, the marsupial gills of the female mussel are ruptured, and the fertilized eggs come loose and attach themselves to the fish – the host fish is infected- learn more https://molluskconservation.org/MUSSELS/Reproduction.html
- how does a fresh water clam breath-In the summer when mussels are ready to reproduce, the males merely release sperm into the water, and the females catch what they can. The sperm is siphoned by the female and used to fertilize her eggs internally.

http://www.fishwild.vt.edu/mussel/research/life_history.html - Freshwater Clams for Natural Filtration-Native to temperate freshwater rivers and lakes around the world, the freshwater clam is a bivalve mollusk that acts like a living filter to help keep aquarium water clean and clear. Freshwater clams such as the Corbicual sp., which originate in Asia and have a brown shell banded in black, help filter your aquarium water by removing detritus and uneaten food from the water column; in doing so, they remove the organic material that would otherwise break down in your system. The end result is reduced nitrite levels and improved water quality. learn more at https://www.drsfostersmith.com/pic/article.cfm?aid=2947

The pros and cons of adding fresh water clams in your filter media.
These are the response of my post at http://www.koiforum.uk/koi-carp-chat/20643-fresh-water-clam-living-filter-media.html
- I’ve heard if you keep them in your pond and they die they become toxic and kill your fish?
- They need cloudy green water as a food source, and hard water. They alse need a mud or sand substrate in the bottom to burrow into. They dont live long in a koi pond with clear water, and as Laura says die and rot in the water causing big problems.
As filters they are pretty useless as they excrete ammonia just like your fish.Would not even consider them in a koi pond myself.
- Below is a link to my thoughts on using swan mussels as pond filters. It is easy to jump to the conclusion that, as swan mussels are filter feeders, they are useful in a koi pond because they filter water to obtain nutrients. But those who advocate that idea clearly haven’t thought the situation through and have ignored the parasitic larval stage where the mussel larvae (glochidia) that are released into the water attach themselves to fish gills to grow and develop. The injury they cause doing this makes them very unsuitable in any pond, let alone a koi pond.There are differences between clams and mussels and I don’t have time to look into the laval stages of clams but my gut feeling is that, in such closely related species, the life cycle will be the same.
Freshwater clams are edible so when you remove them from your pond they will, at least, have some use.
Swan mussels - It’s my understanding that clams don’t have a parasitic larval stage, so don’t directly damage fish in the same way mussels can.
But their other disadvantages and lack of efficacy at biological filtration would make it a pointless exercise anyway in my book - I don’t want to become sidetracked by the distribution of the swan mussel but, if you check, you will find that the Unionidae family of freshwater mussels have worldwide distribution.However, on the subject of clams, I fail to see the purpose of adding clams to a pond. Their natural behaviour is to bury themselves in mud or silt so, unless you intend to allow the pond to become dirty, with all the associated parasite problems that would bring; the environment would be unsuitable leading to their early death.
I also did a quick Google for the life cycle of freshwater clams and, as I suspected, I found references to a parasitic larval stage. Click this for a description:

Corbicula fluminea is a species of freshwater clam, also known as
Asian clam, Asiatic clam, golden clam, golden freshwater clam,
prosperity clam, and good luck clam.
This clam species is native to Asia, and has been introduced into
many parts of the world, including South America, North America and Europe.
Asian golden clams are the more popular species of freshwater
clams today, as they offer a great choice for hobbyists seeking the “unusual”.
This ornamental species introduces a delightful golden coloration
to the aquarium and the opportunity to observe unusual and entertaining behavior.
They have the typical oval-triangular clam shape, with a dorsal “beak” or umbo at the peak of the shell.
The outside of the shell is olive, or yellowish to black-brown
how often do freshwater clams reproduce
resources from animals.mom.me
Freshwater clams, or mollusks, have a very unique way of reproducing. Freshwater clams can be miles away from their mate at the time of fertilization.
All clams set their eggs and sperm free in the water, but freshwater
clams depend on the current to successfully create new life.
Fertilization
A male clam releases his sperm upstream. The current moves his
sperm downstream, until it’s drawn into a female clam’s incurrent
siphon and used to fertilize hundreds, sometimes thousands, of eggs.
Glochidia
Inside the female clam’s gills, the fertilized eggs develop into
glochidia, or larvae capable of attaching themselves to fish’s gills. Once the glochidia are fully formed, the female clam releases them
into the water through her exhalent siphon.
From there, the glochidia attach themselves to a fish, where they
live as a parasite until they’re fully formed.
Life on the Bottom
Once the freshwater mussel is fully formed, he detaches from the fish and drops to the lake or river’s bottom.
He begins to grow his armor, or shell. If he’s lucky, he will live a full life. Depending on the species of freshwater clam, this lifespan could be anywhere from 20 to 100 years.
freshwater clams edible
Although most species are edible, freshwater mussels are not as
tasty as their saltwater relatives.
Besides, since they are long-lived filter feeders, pollutants can
settle and build up inside them, making them distasteful and
unhealthy for human consumption.
Are freshwater clams poisonous?
The real problem with eating freshwater clams is that they are
“filter feeders,” constantly ingesting the water around them, filtering
out whatever is in it, and accumulating a variety of substances,
including pollutants and toxins, in their own tissues.
Do freshwater clams produce pearls?
A cultured pearl is mainly a mussel shell bead with a very thin pearl coating.
Although most natural pearls are found in oysters, they also are
found in many different species of freshwater mussels or clams all over the world. … Big washboard mussels usually have pink pearls, as do the wartybacks.

what do freshwater clams eat
Live aquarium plants continuously shed edible plant matter into the water column.
In most cases, feeding a Freshwater Clam naturally occurring edible
material is not enough.
It may be necessary to supplement a clam’s diet with very finely
ground Calcium enriched pellets or tablets, fish flakes or algae wafers.
